When should a motorcycle rider use hand signals?

Using hand signals is crucial for motorcycle riders at specific times to ensure safety and clear communication with other road users. The correct answer highlights that riders should use hand signals when visibility is low or when turn signals are not functioning properly. This practice is essential because hand signals help communicate the rider's intentions regarding turns, stops, and lane changes to drivers and other road users, particularly in situations where electronic signals might not be visible or reliable.

If visibility is low, such as during fog, rain, or nighttime, relying solely on electronic signals may not be sufficient for others to notice the rider's actions. Hand signals serve as an additional layer of safety, making it easier for others to anticipate the rider’s maneuvers, thus reducing the risk of accidents.

Furthermore, if a motorcycle's turn signal malfunctions, hand signals become a necessary substitute to ensure that riders can still indicate their intentions to others on the road. This practice reinforces the importance of communication in maintaining safety while riding, especially in critical situations where visibility issues or mechanical failures occur.

In contrast, the other choices do not encompass the broader context in which hand signals are essential. Riding in a group or using hand signals only at night may not address the core necessity of signaling in varying visibility conditions
